MEASURING-FAUGET FOR URNS.

7 Specification of Letters Patent.

Patented July 4,1916.

Application filed May 15, 1913. Serial No. 767,809.

To all whom it may concern:

Be it known that I, HENRY D. KELLY, a

citizen of the United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Measuring-Faucets for Urns, of which the following is aspecification.

This invention relates to dispensing valves and has for its object avalve for cream dis pensing cans which will operate with a minimumamount of dripping to deliver measured quantities of cream .in quicksuccession.

Another object is to provide means for agitating thecontents of thedispensing can through the operation of the valve.

With these objects in view, the invention consists of certain novel andpeculiar features of construction and combination as hereinafterdescribed and claimed; and in 'order that it may be fully understoodreference is to be had to the accompanying drawings, in which Figure 1,is a vertical section, partly broken away, of a dispensing can providedwith one form of my improved valve. Fig. 2, is a vertical sectionthrough the faucet portion of a can, showing another form of valve, theoperating lever and lever connections being shown in side elevation.Fig. 3, is a plan view of the parts shown in Fig. 2.

Referring to the drawing, the dispensing can 2 for cream or other liquidhas its bottom 4 provided with a channel portion 6, leading to thedischarge opening of the can. The discharge opening of the channelportion 6 is surrounded by a threaded collar 8, which is securely andtightly fastened in place about the opening by means of screws 10 andpacking 12.

Extending into the opening to the channel portion 6 and threaded toengage the collar 8 is a faucet casing 14, equipped with a nozzle 16,the opening into this nozzle being bridged by a series of ribs 13.

In the form of the invention shown in Fig. 1, the nozzle 16 is providedwith a lug pin 23, this lever having a handle 28 and being pivotallyconnected intermediate its ends by a pin 30, to the outer end of a rod32,

the other end of which is threaded into the body portion of a valve 34.The rod 32 operates through an. opening 36 in a flanged cap 38 which issuitabl threaded to engage and close the outer en of the casing 14.

The body portion of the valve 34 is of smaller diameter than the casing14 and is provided with a pair of annular flanges spaced apart adistance sufficient to give the valve' the required measuring capacity,the amount dispensed by each operation of the valve being determined bythe size of the space inciosed by the body portion 34, the flanges 40and the casing 14, when the valve is traveling from its receivingposition shown in the dotted lines in Fig. 2, to the position ofdischarge shown in full lines in said figure.

In order to give the valve a tight fit in the casing 14, packing rings42 are clamped against the inner faces of the flanges 40 by means ofrings or washers 44 and collars 46,

one of which is threaded upon the rod 32 and the other upon an extension48 of the valve body 34. This extension is of suflicient length toengage one arm of an agitating lever 60 the other arm of which carries aplate 62 which the lever is designed to osciilate in the bottom portionof the can as movements are imparted to the lever by the valve, thelever being mounted by means of a pin 64 journaled at its ends inrecessed lugs 66 carried by the bottom of the can.

In Fig. 2, I show the lever 26 pivoted at its lower end to the pin 30and intermediate its ends to a link 22 by means of a pin 24, the otherend of the link being pivoted on a pin 20 carried by a pair of lugs 18formed on the upper side of the casing 14. In this form the extension 48of the valve body 34 is suitably tapered to engage a socket 50 in theground disk 52 formed on the end of the plunger 54 which slides throughan opening in the cross bar 56 extending across the channel 6. The disk52 is of a diameter adapted to close the opening into the casing 14 andserve as a check valve therefor, the plunger 54 having a slight looseplay in its bearing'in the cross bar 56 so that the disk may be properlyseated against the end of the casing and also have a bearing along thebottom of the channel 6. This plunger bar 54 is recessedat 58 to receivethe end of the agitating arm 60.

In the operation of the faucet shown in Fig. 1, the valve remainsnormally in the position shown with the lever extending rearwardlytoward the tank. In this position the cream may enter and fill the spacebetween the flanges 40. As the lever 26 is moved outward the rear flangewill close the opening into the space between said flanges before theforward flange opens communication with the nozzle. The valve nowcarries a quantity of liquid which is 'definitely measured by the spaceinclosed by flanges 40, casing 14 and body 34, of the valve anddischarges the same as soon as this space is open to the nozzle by theforward flange 40 crossing the outlet through said nozzle, thisdischarge being permitted by the air vents 68 through the casing 14opposite the nozzle. Immediately after the forward movement of the lever26 to discharge the cream, this movement is reversed to restore thevalve to its original position, and in this return movement of the valvethe forward flange 40 carries with it all cream adhering to the innerwalls of the valve casing in the vicinity of the nozzle, so that none ofit may be allowed to drip out through the nozzle opening. At the sametime that the lever is operating the valve in this manner. the extensiona8 operates the agitator by first releasing the same to allow it to rockdownward and afterward reengaging it to rock it back into originalposition.

In the operation of the faucet as shown in Fig. 2, the valve remainsnormally in the full-line position shown in said figure, with the lever26 extending rearwardly toward the tank. On throwing the lever to thedotted line position the valve is forced to the rear so as to projectinto the channel 6 far enough to open the space between the -flanges 40to the liquid in said channel as 7 shown by the dotted lines.Incidentally this movement of the valve brings the extension 48 intoengagement with the disk 52 so as to force the latter and the plunger 54backward to operate the agitator as represented by the dotted lines insaid figure. Now as the lever is thrown back into original position, thevalve advances toward its full line position, the weight of the plate 62meanwhile forcing the plunger 54 and disk 52 forward to close furthercommunication between the channel 6 and casing 14 as well as to relievethe valve from any pressure due to the liquid contents of the can. Thusa measured quantity of the liquid is discharged by the valve, as in theother mode of operation.

It will thus be seen that by applicants device a definite quantity ofliquid is dispensed at each operation ofthe valve, and this operationcan be carried on as fast as desired, the contents of the can beingagitated for each operation of the valve.

The apparatus is especially desirable for restaurant use where cream isdispensed, as the waste of the cream by dripping out between operationsiseflectually prevented by the action of the valve during the backmovement in removing all of the cream adhering to the inner walls of thecasing.

From the foregoing it will be apparent that I have produced a dispensingvalve em-' bodying the features of advantage enumerated as desirable inthe statement of the object of the invention, and while the aboverepresents two embodiments of the same, I do not wish to be limited tothe precise construction and arrangement shown but reserve the right tosuch changes and modifications as fall within the spiritLand scope ofthe appended claim:

The combination with an urn having an opening in its bottom, and aradial channel below and communicating with the opening in the bottom, acylindrical faucet casing secured to the urn and communicating at itsrear end with said channel, and provided with a vent opening and afaucet, a reciprocatory spool-shaped measuring valve fitting slidinglyin the casing and adapted to enter the said channel, manually operablemeans for reciprocating said valve so that when in its rearward positionitca-n be charged between its ends with the liquid from the urn andwhich when in its forward position will deliver said liquid to thespout, and a pivoted agitator mounted in the urn and provided with aportion depending into the channel and exerting a yielding forwardpressure on the valve so as to yieldingly re-- sist rearward movementofthe same and gravitate back to normal position when said valve ismoved forward.

In testimony whereof, I aflix my signature, in the presence of twoWitnesses.
